The boiling point elevation is 3.3688 deg C.
The molality of a solution is defined as the number of moles of solute per kilograms of solvent or per kilograms of solvent in a solution. On the other hand, a certain amount of solution serves as the foundation for the notion of molarity. Mol/kg is a common unit of measurement for molality in chemistry.
delta tb = kb* molality of solution
==> delta tb = change in boiling point = (0.253/ 190) * 10^3 * 2.53
= 3.3688 deg C
